Patent DE-3819704-C1 (DE)
IPC: B01D61/00
Filed: 1988-06-09
Granted: 1989-09-28
Abstract: In a filtration apparatus for concentrating acidulated milk, a filter unit is located between a pump and a backpressure valve. The pump used is a displacement pump, even though the liquid to be filtered would, according to its viscosity value, permit a conventionally used centrifugal pump. During an operating period, the backpressure is gradually increased so that, in spite of increasing coverage of the filter with suspended, dissolved or emulsified constituents, the permeate flow through the filter remains constant. Owing to the characteristics of the displacement pump, the delivery rate remains the same in spite of the increasing backpressure, so that the purification effect of the delivered liquid on the deposits in the filter also remains the same. An extension of the possible duration of an operating period is achieved in this way. <IMAGE>

Patent DE-4417936-C1 (DE)
Inventor: SAUTHOFF GERHARD DR
IPC: C22C19/03
Filed: 1994-05-21
Granted: 1995-12-07
Abstract: A nickel-aluminium intermetallic basis alloy has a structure mainly made of the binary phase NiAl and further contains the elements chromium and tantalum. The total proportion of the elements chromium and tantalum amounts to maximum 12 % by atoms. The preferable content ranges lie from 0.3 to 3.8 % by atoms tantalum and from 1.0 to 9.0 % by atoms chromium. The nickel-aluminium intermetallic basis alloy is characterised in particular by a high oxidation resistance at high temperatures, such as 1350  DEG C. It is therefore suitable for producing pieces exposed to a high and continuous thermal stress, such as gas turbine blades. This high oxidation resistance allows additional anti-oxidation layers to be dispensed with.

Title: The construction is for sealing a plate against wall of container in which bitumen or material containing tar are recycled, such as roof-covering material, with possible inlays such as polyester tissue and similar
Inventor: APPELS DANIEL
IPC: E01C19/10
Filed: 2007-05-14
Granted: 2007-08-01
Abstract: The construction is for sealing a plate (9) against the wall of a container in which bitumen or material containing tar are recycled, such as roof-covering material, with possible inlays such as polyester tissue or similar. Sealing is achieved by a spiral spring (1) fitted above and beneath the longitudinal periphery of the tank plate and presses against the tank wall (2) and in which rollers (3) are fitted, which with reduced clearance fit in the internal diameter of the spiral spring winding (4). The clearance between the plate in the container and the tank wall has to be reduced in order to prevent dirt from the recycled roof covering above the filter plate emerging during the filter movement of the plate and thereby fouling the recycled bitumen above the filter plate.
